Deceptively billed as the Raleigh Music Festival, this lineup of nineties R&B legends is nothing more than date night set in an arena. But if Bell Biv Devoe can have a smash hit (“Run”) in 2016, why can’t these legacy acts enjoy their own version of contemporary visibility? After all, Keith Sweat’s moans are eternal, Avant’s pleading remains useful, Jodeci is forever beloved, and Mint Condition’s live shows still outperform most of the new R&B stars’ sorry excuses for musicianship. “An R&B Celebration in Raleigh” seems more apt. —Eric Tullis
